| In the business of commercial and industrial heating, Applied Air stands out as an expert in gas heating technology Since 1975, Applied Air has been providing cost-effective, reliable hating solutions. Our flexible, "modular" IF Indirect Fired heating systems add warm, fresh and clean air to your work environment at the highest practical efficiency of 80%. |
| Improves Comfort Anywhere |
Replaces Indoor Air |
| IF units are available for indoors (IF), outdoors (IFW), or roof curb mounting (IFR). You can even add DX or chilled water cooling coils for a total comfort solution. |
The IF line replaces indoor air that can become chemical laden in a painting or processing operations, but without adding dust. |
| Replaces Lost Heat |
Heats Small or Large Buildings |
| Large volumes of exhaust air from kitchen hoods or industrial processes take away lots of heat from the space. IF uits replace the heat efficiently. |
With airflows from 2,500 to 94,000 CFM and heat outputs from 350,000 to 6,000,000 BTUH, you can heat any size building. |
| Heats Without Condensation |
 |
| The IF product line operates at efficiencies of 80% in order to avoid the highly corrosive effects of condensation inside the heat exchanger tubes. Efficiencies over 80% can cause serious problems for normal heat exchanger materials. |

| How Indirect Fired Heating Works |
 |
| Indirect Fired gas heating works by transferring heat from a gas flame to a steel chamber and then to the supply airstream. Each transfer of heat results in a loss of efficiency, and some of the original gas flame heat is lost. The amount of loss can be minimized by: |
| • |
Using a powered burner to spread the flame deep down the steel chamber. |
| • |
Pulling the flame heated air evenly through all of the steel tubes by using an "induced" draft fan. |
| • |
Exposing the supply air to as much tubing as possible by using multiple "passes". |
